Hi Gaetan,

The package in CGAL operates on polygons with straight line edges,
but I think the algorithm is extensible to circular arcs. After all
the offset at a circlar arc will result in a circular arc with
the radius equal to the sum of the offset and the current radius.
Let me check internally, how big the effort would be to get there.
